That's not what 0!=1 means in math, the ! means factorial, which is to multiply by decreasing positive integers. Here's the definition:

n! = n x (n -1) x (n - 2) x . . . x 2 x 1

So, for people starting to learn calculus/math, being told that 0!=1 makes no sense

And that's why we need spacing. 0 != 1 is very different from 0! = 1

Ah. ! for factorial was not an obvious parse. I suspect it has alternative meanings in mathematics as well.
